- MACHINE FOR HOLDING AND F sEDINGsRUsH-eAoKs. I

Be it known that I, HERMAN'A. STEIERT, :a citizen of the United States, residing at Sharon Hill, county of Delaware, State of- Pennsylvania, have invented a new and useful Machine for Holding and Feeding Brush-Backs, of which the following is a specification. l r

I My invention relates to a new and usefulmachine for holding a brush-back and feeding it to a brush making machine,'in order that holes may be bored in the back and the tufts inserted, the back being" presented automatically in proper position for this purpose. V

- It will be understood that the machine is adapted for feeding the brush back to a machine for boring the openings therein-or for feeding, the brush back to ajmachine for insertin'g the bristles into the holesso bored.

It further consists of other novel features of For the .purpose of illustrating '"my invention, I have shown in the accompanying drawings, one form thereof which is at present preferred by me, since the same will be found inpractice to give satisfactoryand reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously;

Similar numerals of reference indicate corv responding parts in the figures.

Referrlng to the drawings: 1 designates the frame of the machine which is formed in any suitable or"desired manner and which, is adapted to be supported at a respect to a brush making machine, which my be ofa type either for boringtheholes in the brush-back orfor inserting bristles in the holes, so .bored. It will bev understood that the frame suitably supportsandcarries proper sequence and at the proper timeto "accomplish the desired results.

v2 designates arbed frame carried by the frame 1 ,jupon,which ismovably mounted' and guided a movable bed 3 which is adapted to be reciprocated toward and away from the. brush machine at proper intervals. In-

order to accomplish the reciprocation, I have suitable point in any desiredmanner with I I here shown an arm 4; extending from said bed and carrying a roller 5, Which is enjg agedby the camface 6 of acam 7 carried. .on ,the. shaft8, to which power is suitably .applied in any desired manner, and by the rotation of the cam 7, the bed 3 and all 'of the p'artscarri-ed thereby Twill b'e recip'rocated', at predetermined and desired inter-i vals.

9 designates a j table or carrier mounted upon said bed, 3; for lateral movement thereon and guided j for such movement in any suitable or desiredmjanner, as by the dovetailed connection Supported on {said table 9 in any suitable or desired manner s a shaft 11, upon which is'mounted pinion 12 and a. casing 13, to one end of which is connected a spring 1 1, the opposite end of which is connected with shaft 11 in such a manner that by the rotation of the shaft 11 in one direction, the spring is wound up, that is, the tension of the spring is increased so that when the shaft is released, the spring returns to its normal position and throws out the brush-back support, as will be described. Also mounted upon the said shaft 11 is the clutch, which is so arranged as to assist in turning the said shaft 11, and as here shown, the clutch is formed of a casing 15 connected with the shaft 11, and within the casingare rollers 16, seated in recesses in a movable ring 16*.

17 designates a cam member having cam faces corresponding in number to the number of rollers.

booster 19 actuates the arm 18 in the direction indicated by the arrow in Fig. 6, the

cam member 17 is moved to cause the cam faces thereof to move the rollers against the casing 15 on the shaft 11 causing a bite, thus imparting a movement to the shaft to assist in the rotation thereof. The ring l6 is resiliently held by a spring 17*, so that it yieldingly holds the rollers in position to be engaged by the cam faces of the member 17.

ently thereof, and said plat -20 on its lower face is provided with a plurality of engaging means or shoulders spaced laterally thereon and situated at different points longitudinally in order that the proper step by step inward movement in series may be imparted to the said plates 20 and 21, as will be hereinafter described. The plate 21 is provided with asuitably shaped recess 23 for receiving the brush back, and is provided with looking members 2stadapted to be manually actuated to engage with the brush back to lock the same in position or to release the same. At a suitable point upon the lower face of said plate 21, I provide a series of eX- tended engaging members. shoulders or abutments 25, whichgas will be understood from Fig. 1 1. are suitably spaced apart and the ends of which are in stepped relation to each other order that the end of each abutment may extend a suitable distance beyond the end of the next adiacent abutment.

26 designates a. guider mounted on the bed 3 and positioned to successively engage with the different engaging abutments of the plate21 and to successively release the same at the proper time, as will be hereinafter described. 1

An arm 18 is connected with the cam member 17, so that when the cam Mounted on the table 9 are the hangers 27, which support a shaft 28, on which is secured a drum 29, on the periphery of which are teeth suitably locatedin order that they are circumferentially and laterally spaced in relation to each other, as will be clearly seen from Figs. 2 and 4, in order that when the drum is rotated, the teeth are caused to successively engage with one of the engaging faces or shoulders 22, and to move the same in order to impart step by step inward movements in series to the brush-back support, each tooth 30 in its turn being moved into and remaining in engagement with its proper shoulder or abutment 22 of the support until by the rotation of the drum 29 the tooth is carried downwardly away from its engagement and so releases the support, as will be understood from Fig. 5. is the teeth 30 are peripherally spaced on the drum 29 and are also spaced laterally thereon, as will be clearly understood from Figs. 2 and 4, the rotation of the drum will cause a tooth to engage with the proper shoulder to impart a series of inward move ments to the support and when that tooth has moved away from its engagement the next succeeding tooth will have moved to a position to engage with the next shoulder or abutment at the proper time to'impart a series of inward movements to the support, and when this tooth has been moved away the next tooth has been properly located to engage with the next shoulder, which will be apparent.

In order to actuate the drum 29 at the proper time, I have provided a series of teeth or a ratchet 31 in suitable connection with the drum, and with which a pawl 32 is adapted to engage, said pawl being carried bv an arm 33 mo-vablv mounted on the shaft 28 and with which is connected a lever 3-1 adapted at each reciprocation of the bed 3 to engage the bar r other suitable point on theframe 1 of the machine, to impart a forward movement to the pawl suflicient to rotate the drum the required distance in the direction indicated by the arrow in Fig. 5, and so advancing or moving the brush-back support ste by step inwardlv. the required distance, it being understood that the reciprocation of the bed 3 and the actuation of the drum 29 are suitably related and timed in order to impart the proper movement at the proper time to the support for the bruslrbaclr. I

36 designates a pawl suitably carried by one of the hangers 27 and adapted to engage with the teeth of the ratchet 31 to permit rotation in one direction and to prevent iin proper return movement of the drum 29. Carried by either of the plates, here shown as the plate 20, is a rack 37 in suitable engagement with the pinion 12, in order to rotate the shaft 11 as the brush-back support is moved inwardlyyand when'the brush-back support is releasedby a tooth 30, the spring 14 acts to throw back the support by the action of the pinion 12 on the rack 37. Connected with the table 9is' 'a ratchet 38, the teeth of which are adapted end of the lever 40 is a roller bearing against an edge of the cam 7,, which is pro-.

vided with a side cam extension or belly 46 adapted at intervals to engage'with the roller 45 to actuate the lever 40, it being understood that as long as the guider 26 is in engagement with one of the engaging abutments 25 of the brush-back support, the

support is held against lateral or side movement and'the pawl 39 cannot move'the ratchet 38. In this event, the'actuation of the roller end of the lever '40 by the cam extension 46 will force the pawl 39 against one of the teeth of the ratchet 38, but as this cannot move, the action will be to forcethe support 4]. outwardly against the tension of the spring 43, the pawl 39 serving as the fulcrum of the lever 40 at that time. When, however, by the inward movement of the brush-back support, the end of the engaging member 25 with which the guider 26 is in engagement has been reached, the bed 9 is no longer held thereby, and the side extension 46 is timed to impart an outward move ment of the roller end of the lever 40 which moves inwardly the other end of the said' lever 40 and the pawl 39 carried thereby," which is in engagement with a tooth of the ratchet 38 will force over the plates 20 and 21 with the table 9 and move the same laterally or sidewise, while at substantially this time, the tooth 30' of the drum 29, which has been in engagement with one of the engaging shoulders 22, will have released the same and the spring 14 will at once act to throw outwardly the plates 20 and 21, so that the lateral side movement and outward throw of these plates forming the support of the brush-back are suitably accomplished and timed. or brush-back support after each side and outward movement inproper positionfor the next series of step by step inward movements, I have provided a series of stepped shoulders 47 on one of the plates, here shown 7 as the plate 21, and I have mounted-a stop 48 on the frame 1, and the side movement and outwardthrow will cause the proper shoulder 47 to successively engage thestop In order to'locate these plates 48, as will be evident and these parts will thus limit both the side and outward movements. p f

It willbe understood that the means for imparting the inward series of step by step movements, here shown as a drum and coacting devices, is arranged in order that 'the support for the brush-back will be moved inwardly step by step and with suit able dwells in'o-rder that the series of'holes may be drilled, or, in'order that the bristles may be'inserted in thesaid holes, depending upon with which character of machine the device is being, used. a g

I have shown a spring 54 connected with the lever 40 torholding the same in and returning the same to proper position, and I have also shown a pinion or gear 55 mounted on a shaft 56,.saidpinion'55 being in engagement with' the teeth 57 on the ratchet 38, while on saidshaft 56 is mounted a hand lever 58, so that when it is desired, when the machine isnot running, the lateral move 'ment may be madeby'hand. I In order to positively stop the machine at the proper time, I have provided arod 59, one end of which is connected with a pedal not shown controlling the clutch'not shown for starting and stopping the machine, the opposite end of which rod is movable in an opening 60 in*the frame 1. A slide plate 61 is movably mounted on the frame 1 having anopening 62therein'and a spring 63 normally holds said opening 62 out of alinement with the'o'pening 60 in the frame 1, so that when the machine is in operation, the rod 59 abuts the slide 61 and isjheld in its lowermost position holding the pedal in starting and operating position. Y 64 deslgnates an arm carried by the brushback support and which moves inwardly therewith, and is so positioned that at the proper time, it engages with a latch 65 car ried on the plate 61 and forces the same inwardly against the tensionof the spring 63,

and thus moves the opening '62 into alinement with, the opening 60, whereupon the pedal will force the rod 59 upwardly and the machine will be automatically stopped.

In order to lock the drum. 29 when the machine is stopped to prevent the further rotation of the said drum, I provide a notch which" normally bears against the edge of the drum, due to the spring '68., until the notch 66 is reached, when the spring 68 forces the dog 67 into said notch and so locks the drum against rotation. WVhen the bed-3 is moved to startingposition, the-dog 67 engages a stationary member 69 on the frame 1,.which is so positioned as to remove '66 therein, and I have provided a dog 67,

the dog 67 from the notch 66, see'Fig. 4,;

and the parts are ready for operation again.

The arm 18 is here shown as provided with a springmember 70, whichis so located that it will be struck bythe cam booster 19 if the arm 18 for any reason should not return to its proper position. In order to limit the rearward movement of the arm 33 carrying the pawl 32, l have provided a stop 71 on one of the hangers, which is en gaged by a pin 72 carried by the arm 33, so that the latter, when returned to position by the spring 73, will always be located in proper position, ready for the next operation.

As I have illustrated in the drawings a portion of a machine-for inserting the bristles, the operation of the device will be described with respect thereto. it will be understood that the device, as previously stated, can be used for feeding brush backs for boring the openings or holes therein, for inserting the bristles into the holes so bored, or both. As above stated, in the present instance, I have shown a portion of a bristle inserting machine which forms no part of the present invention but in which it will be understood that the bristles are properly fed to the nozzle 49 and therefrom into the holes of the brush back at the proper time, and which operation is suitably timed with respect to the operation of the feeding machine. The brush back 50 in which the holes have already been drilled, having been inserted and locked in position upon the support 21, and the parts be ing in the position seen in Fig. 1, it will be understood that the machine is ready for operation with the first line of holes in suitable positoin to be located beneath the nozzle 19 with the first tooth 30 of the drum 29 in engagement with the first of the series of abutments 22 on the plate 21. The machine having now been started, suitable motion will be imparted to the shaft 8 as well as to the brush making machine. The

' latter will be operated to cause the bristles which have fed to the nozzle 49 to be inserted in the first hole 51 which is beneath the nozzle. The cam 7 will be suitably rotated to impart a reciprocating movement to the support 21, which will remove the ends of the bristles from the nozzle and wi l cause the lever 34 to be moved to a position to engage with the bar 35. This will cause an actuation of the pawl 32 carried by the lever 8st to rotate the drum one step inwardly, while at the same time, the rotation of the cam booster 19 will cause it to lift the rod 18, causing the clutch to engage and assist in the rotation of the shaft 11 in the same direction of rotation as that imparted thereto by the inward movement of the rack 87 carried by the support and which is in engagement with the gear 12 on the said shaft. This inwart movement will locate the second opening 52 beneath the nozzle, and the brush making machine will again insert a bunch of bristles into the second opening, whereupon the cam 7 again reciprocates the support 21, again causing the lever 3% to engage with the bar 35 to impart a suitable amount of rotation to the drum 29 to again move the support inwardly another step thus locating the opening 53 beneath the nozzle 49, while at the same time, imparting further rotation to the shaft 11, it being understood that by each of such rotations of the shaft 11, the tension of the spring 14 is increased. The brush making machine will again be operated to insert a bunch of bris tles in the said third opening 53, whereupon the cam 7 will again reciprocate the sup port 21. This reciprocation will remove the guider 26 from its engagement with the first abutment 25 on the support 21 and the drum 29 will have been rotated suiliciently to move the first tooth 30 away from its engagement with the first shoulder As the guider is no longer in engagement with an abutment 25, thereis nothing to prevent the lateral or side movement or the support and the cam extension 46 on the cam 7 is so timed that it will at this time engage with one end of the lever 40 to move the same in the proper direction, which will cause movement of the other end of the lever 40 in the opposite direction, and as the pawl 39 is in engagement with the teeth of the rack 38, it will move the support 21 laterally. At the same time, as above stated, as the first tooth 80 is no longer in engagement with the first shoulder 22, the spring l l will throw the support outwardly in the opposite direction from its inward movement, and these two movements outwardly and sidewise, or laterally, will throw the support so that the first notch or shoulder 4-7 on the support is thrown into engagement with the stop 48 and the support and the various parts are thus located in position. in order that the guider 26 will have been brought into proper engagement with the second of the engaging abutments 25 and the next or second tooth 30 on the drum 39 is in engagement with the next adjacent engaging shoulder 22, while the first hole of the second row of holes will be located beneath the nozzle i9. When the said extension 46 of the cam 7 releases the end of the lever 40, the springs connected therewith will move the pawl end thereoi' in order to cause the said pawl 89 to be in engagement with the next succeeding tooth on the rack 38 and ready for the next side or lateral throw. The same cycle oi operations just described will take place until the second series of holes have been filled or receive bristles, when the support is again moved sidewise and outwardly to cause the second shoulder 47 to engage with the stop 48, so that the guider 26 is in en gagement with the next or third engaging iao abutment 25, while the next or third tooth 30 of the drum 39 is in engagement with the next or third shoulder 22 and the first hole of the third series of holes is in position to receive the bristles. These operatitons are repeated until all of the holes in the back have received the bristles, at which time, the arm 64 carried by the support, will have engaged with the latch 65 carried on the plate 61 and forces the same 1nwardly to locate the opening 62 in the plate 61 in.

line with the opening 60, whereupon the rod 59 moves upwardly and passes through the opening 62 and this movement of the rod releases the pedal controlling the clutch and the machine is stopped. At this time, it will be understood that the rotation of the drum 29 has been such that the notch 66 in the drum will be in line with the dog 67 which heretofore was in engagement with the sideedge of the drum,and the dog 67 is forced thereint-o by the spring 68, so that the drum is thus locked against rotation.

It will be understood that the vsupport 21 is now in its extreme left hand position with the last shoulder 47 in engagement with the stop 48, and the handle 58 in engagement with the pinion 55 will have been moved substantially 90. Inorder tonow'return the parts to their starting-position, the operator, presses inwardly upon the support 21, and at the same time,.by grasping the handle 58 and rotating the same, to return it to the position seen in Fig. 2, will cause the support 21 to be moved laterally to the right in said figure by reason of the engagement-of the teeth of the pinion 55 with the rack 57. This action will return the support 21 to its initial position, as seen in Fig.

1, and at the same time, by releasing the,

support. 21, the spring 14 will throw it outwardly until the first tooth 30 will have engaged with the first shoulder22 on the support, it being understood that thisfirst tooth 30 has been moved to its proper position for such engagement by the previous rotation of the drum. At this time, theguider 26 will again be inengagement with the first en a in abutment 25 and the arts ready for the next operation. Bythe return side and outward movement of the support 21, the dog 67 will be caused to engage with the stationary member 69 on the frame 1 to remove the same from its engagement with the walls of the notch 66 so that the drum may be rotated at the proper time. WVhen vit is desired to start the machine the oper-' ator depresses the controlling'pedal and the rod 59 is lowered, removing it from the opening 62, immediately upon which the spring 63 throws the plate 61in the opposite direction, locating the solid portion of the plate 61 over the top of the rod 59 and is thus held in position in order that the machine will operate continuously until the arm 64 again contacts with, the latch 65. The same cycle of operations is then repeated, as above described. The completed brush can be removed at any time,-as for example, after. the support 21 has been moved to its initial position and a brush back to be filled can then be inserted. 7 v

From'the above it will be understood that. the brush-back support is moved inwardly step by step in series, is released at the proper time in order to be moved laterally is shown, in which the end holes are not quite in line, as will be seen, although this may be varied, depending upon the character of the brush. It will be noted that the 7 brush back is situated angularlyin the sup port, by reason of whiclrthe back may be properly presented in a convenient and easy manner to accomplish the desired result.

As described with respect to the'bristle insertion, it will beunderstood that in boring the holes the brush back is fed inwardly in serial step by step movements and is moved laterally at the end of each series tolocate the back properly beneath a bor--.

ing tool, the operating of the parts pro-' iding for theproper movements and dwells" and being timed with respect to the opera- 1 tion of the boring tool. I i

It will now be apparent that I have I vised a novel and useful machinefor hold-J ing and feeding brush backs which. em-

bodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which will be found in practice to give satisfactory and reliable results, itis to be understood that the same is susceptible ofmodification in various, particulars without departing from the spirit or scope of the invention or sacrificing any of its 'advan-' tages.

Having thus described my invention, whatI claim as new and desire-to secure. by Letters Patent, is
